are inactive for over three months, in Hybrid Columnar Compressed (HCC) format.
Which three storage options support the use of HCC?

A.
ASM disk groups with ASM disks consisting of Exadata Grid Disks.

B.
ASM disk groups with ASM disks consisting of LUNS on any Storage Area Network array

C.
ASM disk groups with ASM disks consisting of any zero padded NFS-mounted files

D.
Database files stored in ZFS and accessed using conventional NFS mounts.

E.
Database files stored in ZFS and accessed using the Oracle Direct NFS feature

F.
Database files stored in any file system and accessed using the Oracle Direct NFS feature

G.
ASM disk groups with ASM disks consisting of LUNs on Pillar Axiom Storage arrays

Explanation:
HCC requires the use of Oracle Storage – Exadata (A), Pillar Axiom (G) or Sun ZFS
Storage Appliance (ZFSSA).
Note:
* Hybrid Columnar Compression, initially only available on Exadata, has been extended to support
Pillar Axiom and Sun ZFS Storage Appliance (ZFSSA) storage when used with Oracle Database
Enterprise Edition 11.2.0.3 and above
* Oracle offers the ability to manage NFS using a feature called Oracle Direct NFS (dNFS). Oracle
Direct NFS implements NFS V3 protocol within the Oracle database kernel itself. Oracle Direct
NFS client overcomes many of the challenges associated with using NFS with the Oracle
Database with simple configuration, better performance than traditional NFS clients, and offers
consistent configuration across platforms.
